Key takeaways
  • If a will was altered or marked in some way, Ontario uses Form 74E, the affidavit of condition of will or codicil.
  • The original will must be attached to the affidavit and filed on paper.
  • Court staff check for other applications, objections and any more recent will.
  • Whether a particular change has any legal effect depends on the facts, so get advice before filing.

You have found the original will and something is off. A name is crossed out, a number has been written over, or there are notes in the margin in a different pen. As executor, you need to know how this affects the probate application.

This article explains the evidence Ontario's probate process generally asks for when a will has been altered or marked, and how to prepare. It does not say which changes count and which do not. That depends on the facts of your will and is worth confirming with a lawyer.

Why alterations matter to the court

The court is being asked to grant authority based on the will. If the document looks different from when it was signed, the judge needs to understand what the document looked like and when and how it came to look that way. The condition of the will is evidence.

Ontario's forms deal with this directly. Form 74E is the Affidavit of Condition of Will or Codicil, and it is used if the will was altered or marked in some way. It is listed among the supporting affidavits in the standard probate package.

What the affidavit of condition is for

An affidavit of condition is a sworn statement about the physical state of the will. The person swearing it describes what they see and what they know about it. Who should swear it, and what it should say about each mark, is a point to settle with a lawyer, because the wording affects how the court reads the document.

The original will must be attached to the affidavit as an exhibit. Even when the application is emailed, the original will must still be filed on paper at the court location where the application was filed.

What you findLikely supporting document
Crossed-out words, writing in the margin, added or changed textForm 74E, affidavit of condition
Entire will in the deceased's handwritingForm 74F, affidavit of handwriting and signature
Normal signed and witnessed will with no marksForm 74D, affidavit of execution

If the will is both handwritten and marked up, more than one affidavit may be relevant. A lawyer can tell you which combination fits your situation.

The rest of the application

The affidavit sits within the usual package. That includes the following.

For estates valued at $150,000 or less, the small estate process applies, using Forms 74.1A, 74.1B and 74.1C, and Form 74E is still the affidavit used if the will was altered or marked. Otherwise you apply for a Certificate of Appointment of Estate Trustee.

Who must be told, and what can slow things down

Before filing, send a copy of the signed application to each beneficiary, meaning everyone entitled to a share, to their last known address. People who would lose out because of an alteration are the ones most likely to object, so accurate notice matters. For a small estate, the copy must go out at least 30 days before filing.

If a minor has an interest, the Office of the Children's Lawyer must be served, and the notice should include a copy of the deceased's entire last will. If a beneficiary is an incapable adult, the Public Guardian and Trustee may also need to be served.

Ontario says applications are typically processed within 15 business days, longer if documents are missing or a judge must decide an issue. A refusal comes as Form 74O with reasons. If someone files an objection on Form 75.1, the applicant must serve Form 75.3 on the objector.

What to do next

Once the certificate is issued, the Estate Information Return is due within 180 calendar days, even if no tax is payable.

Frequently asked questions

Do I have to tell the court about changes on the will?

Ontario provides Form 74E for a will that was altered or marked in some way, and the original will is attached to it. How this applies to your particular marks depends on your situation, so it is worth confirming with a lawyer.

Does an alteration automatically cancel part of the will?

Whether a particular change has any legal effect depends on your situation, so it is worth confirming with a lawyer. The court is given a sworn description of the document's condition so it can decide.

Can I send in a photocopy with the changes visible?

No. The original will must be attached to the affidavit and filed on paper, even when the application itself is emailed.

What if a beneficiary disagrees about the changes?

They can file an objection on Form 75.1, and the applicant must then serve Form 75.3 on the objector. Disputes like this are worth taking to a lawyer early.
